PHPUnit assertSame()函数
assertSame()函数是 PHPUnit 中的内置函数,用于断言实际获取的值是否与预期值相同。如果预期值与实际值相同,则此断言将返回 true,否则返回 false。如果为真,则断言的测试用例通过,否则测试用例失败。
句法:
assertSame(mixed $expected, mixed $actual[, string $message = ''])
参数:此函数接受三个参数,如上所述,如下所述:
- $expected:此参数是代表预期数据的任何类型。
- $actual:这个参数是代表实际数据的任何类型。
- $message:此参数采用字符串值。当测试用例失败时,此字符串消息显示为错误消息。
下面的例子说明了 PHPUnit 中的 assertSame()函数:
示例 1:
PHP
assertSame(
$expected,
$actual,
"actual value is not same as expected value"
);
}
}
?>
PHP
assertSame(
$expected,
$actual,

);
}
}
?>
